Product overview
Description
The STEVAL-LLL013V1 is a 7x25 LED matrix board controlled by two STP16CPC26 LED drivers.
It can display banners in which each pixel can have a different level of brightness (32levels).
The screen refresh rate is higher than 100 Hz. The banners can be scrolled horizontally in both directions for lights effects. The banners are loaded by the use of the STSW-LLL013GUI PC software app.
The STP16CPC26 is a monolithic, low voltage, 16-bit constant current LED sink driver with a serial input/output interface.
Two STP16CPC26 drive a 7x25 LED matrix. The two LED drivers are connected in a daisy chain and controlled by the STM32F042K6 MCU, using an SPI IP interface.
The MCU works as a frame generator for the banners, and as a bridge with the PC software app, by implementing a USB VCP device class.
Additional potentiometers on the board allow you to change the brightness of the whole display and the speed of the banner scrolling effects.
To exploit all the potential features of the board, many hardware resources are available, such as pin connectors that deliver additional MCU features, a JTAG interface, and a serial input/output to cascade other LED drivers.
